IRVING S. HART, OF WAVERLY, NEW YORK Application filed MarcnlM, 1912. Serial No. 683,758.

- To all'yuitom it may concern: Be it known that I, IRVING S. HART, a at and useful Improvements in Silos, of which the following-is 'a specification.

This invention relates to silos, and especially to a transportable knock-down silo having such novel and peculiar construction and combination of parts as to'be expedit-iously packed, shipped and assembled in operative position, v

The object of the invention is to provide a combination ladder rung and door-batten brace, and special supporting brackets for the rungs so as to permit the operation of a pair or door locking bars through the bracket's; and to furnish the. door panels with means for operating the bars.

Various other objects, advantages and a improved results will be found in the practical application of the inventien as'hereinafter fully disclosed In the accompanying drawings forming part of this application :-Figure 1 is an elevation of a silo embodying my invention.

Fig.2 is anenlargedi sectional V1W Of part f ,asilo, taken on the dotted line X-X 1. Fig. 3 is a similar View taken on dotted lineY-Y, with the door-rung partly broken away. Fig. 4: is a detail elevation showing the application of the locking device, the dotted lines showing the swinging movement of the cam-lever. -Fig.

5 is a perspective view of the locking device partly broken away. -Figs. 6 and 7 are perspective views. of the respective brackets. Fig. 8 is a detail section showing a packing 9 is a perspective view of one of the blocks. Fig. 10 is a detail elevation of assembled blocks.

The same reference characters denote the same parts throughout the several views of the drawings.

- In carrying out my invention, two posts or beams are set in vertical position on a suitable foundation, and such posts form the door-jambs 1, which also form an abutment for the first and the last tiers of concrete blocks 2. The blocks 2 have one or more pointed anchors 3 projecting therefrom, and the anchors are driven onto the jambs for connecting the said blocks with the jambs.

The said blocks as well as the intervening Specification of Letters Patent.

- t angul'ar lug or projecti H 5 'staves 6, have their jamb to the other so equally distributes the contact 'bet ee g formed in the lower portion of the casing,

mated-6a 9 blocks 4: have .tOIlgLlt} edges which are prefer bl each of all of said bloc jl face thereof, and t meeting edges placed stjth'e a d blockpro ect1ons so as to if a co nntmusanspace or annular chain 'e'r'7, betweenj,the

outer casing, which is fo niedstaXeS,

and the inner wall, .lisfo'rnied by-the blocks. The posts oi' dtoor j ambs are also usedas a means for starting and finishing the sett ng up or assenihlingfof the panels or stavesagainst the wall that the first and the l astista ve is securedfftojtlie respective posts bybolts 8, extending at right angles to the anchors 3, tl irofigh the'postsi and through the said staves' and provided with ayes.

nuts 9, and the intervening panelsxor, are. fitted together in fsuccession from one every other: st avelock :pr j ection,

gru will be 'made. 0 and the said projecti with the block joints ,th of the wall, and the e alinement. Sucharr a ement rite; only th wall and the casing throughout 'th e ght and circumference ot 'the. silo, but; the,

to the top of the silo.

The ladder for the silo is composed of two sets of tubes or ladder rungs. One set of tubes 11 are secured to the door battens12 by means of supporting brackets 13, into which the ends of the tubes are screwed, and

' these b'racketshave a slot 14 through which the door locking-bars are operated. The other'set of rungs or tubes 15 are screwed into angle brackets 16 secured tothe doorstaves bymeans ofbolts 17 and screws 18,

and these brackets have a groove 19, for the binding hoops 21, which extend through the tubes 15. 'Itwill be observed that the brackets 16 extend over the face of the do'dr-staves 1 and have afiange 20: extending across. the

edge of said staves, and that one set of ladder rungs connect and hold the door battens in proper position, and that said rungs also shield or protect the locking device, while the other set of rungs brace the door staves apart and prevent such staves from being affected by operating the hoops.

The door-locking device comprises a plate 22 secured to the door panels or sections 22 against and flush with one of the door bat-.

tens which is provided with a guide 2,3..,.. and., the plate is provided with a like guide24:;"

the plate is secured by means of a pivot bolt 25, upon which is mounted a lever 26, having a double cam head 26 substantially S- shaped, a short locking bar 27 is operated by one of saidcams'28, and a long locking bar 29 is operated by the other of said cams 30, and each of said bars has a head 31 and 32, respectively, for limiting the outward movement of the bars through the brackets 13 and keepers113E, and said heads form a bearing for the It will be seen that the bars are located out of the plane of the pivot bolt; that the short bar is placed above the plane of the long bar; and that the bars are slidable in opposite directions under pressure of the cams for automatically locking the doors simultaneously at each edge thereof. The bars are of such length and the cams are of such shape as to provide for expansion and contraction in the doors or I door-way, so as.

b" Wedge the bars into locked position. I

It is obvious that the doors are locked and unlocked by merelyswinging the cam-lever,

and the doors may be placed and removed as desired or as occasion may demand.

It will be observed that the bars are slid through the-rung supporting brackets 13, and that said brackets ofi-set the rungs from the locking device so as not to interfere with the operation of said device.

It will be understood that this silo may be used with or without the inner Wall, in which latter event the posts are dispensed with and the door-staves or the staves of the door-way are first fixed in upright position, all other features remaining the same.

In. order to make an air-tight joint between the door and the jainbs or door-staves, I provide corrugated soft cork strips 33.

Having thus described my invention what Lclaim as new and desire- :o se ure by Let: ters Patent is 1. The combination with. a silo, a plurality of vertically sliding doors having battens fitting within. the door-way of the silo, and two sets of rungs, of a pair of brackets secured to the battens of each door for hanging one set of the rungs and having a slot in the inner face thereof, brackets secured to the door jambs for hanging the other set of rungs in the same verticalplane with the said door-rungs, a pairvoftl'ocking bars carried by the doors and between'the doors and the door-rungs and sl'idab le through the bracket-slots, a cam-head .-pi voted to the doors, cam-faces on the-head for simultaneously sliding ,the bars outwardly, and a hand lever projecting from the head and separating the cams. ,I"

2. The combination with a silo, and a plurality of vertically sliding doors having battens fitting within the door-way of the silo, of a pair of rung brackets secured to the battens of each door and having a slot in the inner face thereof, a pair of locking bars carried by the doors and slidable through the bracket-slots, a cam-head pivoted to the doors, cam-faces on the head for simultaneously sliding the bars outwardly, and a hand-lever pro ecting from the head and separating the cams.

In witness whereof. I hereunto set my hand in the presence of two witnesses.-

IRVING S. HART.
